The VLAN ID of each VLAN subinterface must match the VLAN ID added by the IEEE
802.1Q-compliant router. The VLAN ID can be any number between 1 and 4096.
Each VLAN subinterface must also be configured with its own IP address and
netmask.
Note: A VLAN must not have the same name as a virtual domain or zone.
You add VLAN subinterfaces to the physical interface that receives VLAN-tagged
packets.
